HAY-PRESS.

SPECIFICATION forming part of Letters vPatent No. 413,264, dated October 22, 1889. i

Application led July 25, 1889. Serial No. 318,619. (No model.)

` Texas, have invented a new and useful Hay- Press, of which the following is a specification. This invention relates to baling-presses;

and it has for its object to provide a device of this class which shall be simple in construction, durable and eifective in operation, and which may be operated with the smallest possible expenditure of power.

The invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a plan view of my improved press. Fig. 2

'is a vertical sectional view taken longitudinally through the press-box. Fig. 3 is a vertical sectional view taken through the pitman, crank,`and sweep at right angles to the sectional view shown in Fig. 2.

Like numerals of reference indicate likeA parts in all the figures.

' 1 1 designate the longitudinal framebeams, between the front ends of which the balingchamber 2 is constructed in the usual manner. The upper and lower frame-beams are connected at their front and rear ends and at intermediate points by vertical post-s 3, and transverse braces a in like manner connect the side fram e-beams. The lower frame-beams are mounted upon sills 5 and upon a laterally-extending base (5, in the outer end of which latter is mounted a vertical shaft or post 7, on which is journaled a crank S. A circular track 9 surrounds the post 7 and serves to support the outer end of the crank 8 or an intermediate portion of said crank, as may be preferred. The vertical posts 3 at the rear end of the frame are connected by a horizontal cross piece or brace 10, to which are secured a pair of forwardly-extending plates or brackets 11, between which the rear end of a toggle link or lever 12 is pivotally mounted. The front end of the link 12 is pivotally connected with the rear end of a similar link 13, the front end of which is in turn pivotally connected with the plunger 14 of the press. Said plunger, which is of ordinary construction, is adapted to reciprocate the materialwhich is being compressed from moving in a rearward direction when th plunger is withdrawn. p

17 designates the pitman, which connects the outer end of the crank `t3 With the connecting-point of the links or toggles 12 and 13, the connection being made in such a manner that when the links 12 and A13 are in line with each other the crank 8 shall be parallel thereto. It follows that with each revolution of the crank 8 the plunger attached to the link 13 will make two beats or pulsations. The pitman 17 is constructed of two end pieces 18 18, connected by a bridge-piece 19, which is located below the said end pieces. This is for the purpose of enabling the horse attached to the machine to step easily and conveniently over the said pitman.

Upon the' bolt 20, which connects the crank 8 with the pitman 17, is securely mounted a plate 21, the sides of which are provided with flanges 2 2, between which `is mounted the sweep 23, which is thus kept in alignment with the crank. 2O is to be mounted rigidly in the outer end of the said crank, while the pitman 17 is connected pivotally with the said bolt. The extreme lower end of the bolt 20 is bifurcated to form bearings for a friction wheel or roller 21, which travels upon the track 9, thereby supporting the weight of the crank, pitman, and sweep.

In operation the horse is hitched 'in the usual manner to the outer end of the sweep, by means of which rotary motion is imparted to the crank for the purpose of operating the press. It will be seen that at the point Where the horse is required to step over the pitman the sweep and the pitman are parallel to and in Aalignment with each other. Owing to this It is obvious that the bolt IOO The power is applied easily and gradually, and is greatest at the point Where it is most needed viz., at the greatest point of compression, which is at the point Where the toggle-links are on a line with each other. Vhen this point is passed, the plunger will return evenly and gradually without rebounding and Without danger of permitting the contents of the balingchamber to bulge out under the feed-opening.

Havn g th us described my invention, what I claim, and desire to secure by Letters Patentj 1sl. In abaling-press, the combination of the frame, the baling-ehamber at the front end of the same, the plunger, the toggle-links connecting said plunger with a cross-piece at the rear end of the frame, a base extending laterally from the frame, a horizontal crank mounted pivotally upon said base, the pitman con` necting said crank with the connecting-point of the toggle-links, said pitman consisting of end pieces connected by a bridge-piece lying in a lower plane than the said end pieces, and an operating-sweep, substantially as set forth.

2. In abaling-press, the combination of the frame, the baling-chamber, the plunger, the

toggle-links connecting the latter With a crosspiece at the rear end of the frame, a base eX- tending laterally from the frame, a crank mounted horizontally upon said base, a bolt mounted rigidly in the outer end of said crank, a pitinan connecting said bolt pivotally with the connecting-point of the toggle-links, a flanged plate mounted rigidly upon the upper end of said bolt7 and a sweep mounted upon said plate, substantially as set forth.

3. In abaling-press, the combination of a reciprocating plunger, toggle-links connecting said plunger with a cross-piece at the rear end of the press-frame, a horizontal crank mounted upon a' laterally-extending base, a pitman connecting the outer end of said crank With the connecting-point of the toggle-links, a sweep mounted rigidly upon the upper end of the bolt, connecting said crank and pitman, a Wheel or roller at the lower end of said bolt,

and a circular track supporting said roller,
